The Water Corporation has revealed further details about plans to dispose of wastewater from Denmark, in Western Australia's Great Southern, after a community backlash forced the utility to axe its original plan.

The Water Corporation's CEO, Sue Murphy, told Parliament this week, she "regrets terribly" that "overzealous employees" moved ahead with plans to dump desalination brine discharge at Perkins Beach without first consulting the local community.

She said the utility was exploring three alternative options, including trucking the brine to the Binningup desalination plant and releasing it in an inlet feeding to the facility.

Other options include dumping the water in unused ponds near Albany or contracting licensed waste handlers to dispose of the brine elsewhere.

Mrs Murphy could not reveal the estimated cost of each option but said the utility was working through its options.
